IMPROVEMENT IN sone-romains.

The Schedule referred to im these Letters Patent and making part of the same.

To all -wlwm tt ma/y concern.-

Be it known that we, A. D. SCHNAGKENBERG and Orro Rosmvnnnnz, of Brooklyn, in the county of Kings, and State 'of New York, have invented a new and improved Soda-Water Fountain; and we do hereby declare that the following is .a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming a .part of this specification. A

The Idrawing represents a sectional elevation of our invention.

This invention relates to a new manner of arranging the valve in the discharge-pipe of a soda-water fountain or bottle, and consists in having the valve at the lower end oi' the discharge-pipe, close above the i bottom of the fountain or bottle.

Heretofore the valves were always arranged in the upper part of the fountain, and the liquid consequently remained in and filled the discharge-pipe, which was not only injurious tothe pipe, but also to the liquid, which decomposed particles ofthe pipe, and -received a disagreeable taste or injurious properties. By hav-l ing the valve at the lower end of the pipe, the said pipe will, when c losed, be entirely emptied, and the aforementioned objections will be entirely overcome.

The invention also consists in the use ofa cap, tted over the upper end of the aforesaid dischargefpipe,

which cap, when screwed down, pushes down the valve-rod, and opens the valve, a spring holding the rod against the crown of the cap. The cap serves to close the upper end of the pipe air-tight, and permits, at the same time, the'easy operation of the valve.

A, in the drawing, represents the discharge-pipe of a soda-water fountain, said pipe extending from the upper end of the-fountain, where itis screwed, or otherwise fastened, to a T-pipe, B, as shown, nearly to the bottom of the fountain.

The pipe B is secured to the neck of the fountain in the ordinary or in suitable manner.

C represents a valve-rod, with a head, a, formed at its upper end, and a valve, b, at itsV lower end, as shown.

Between the head a anda shoulder, c, formed in the pipe B, is interposed a spring, (l, which serves to draw the valve against the lowerend of the pipe A, and to thereby hold the lowerend of the said pipe closed,`the rod C extending through the whole pipe` A, as shown.

Upon the shoulder c may be placed a rubber or elas? tic disk, e, which fits tight around the rod, to prevent the liquid from rising above the disk into the upper compartment of the pipe B.

The spring would then rest upon a metal washer, f, placed upon e, as shown.v

The valve is of suitable construction.

D represents a cap, screwed over the upper end of the pipe B, the spring d holding the head a against ther crown of the cap. By screwing down the cap, the rod will be pushed down and the valve will be opened.

A rubber ring, g, may be interposed between the lower end of the cap anda shoulder on the outside of B to make an air-tight joint when the cap is down vand the valve open.

Having thus described our invention, Vtfhat we claim as new, and desire to secure by Letters Patent, is

l. rlhe valve of a sodafwater fountain, operated by meansoi` a cap, D, screwed over the upper end of the T-pipeB, and by means of a spring, d, as speciiied.

2. The pipes A and B, in combination with the valve b, rod C, spring d, and cap, D, all arranged and operating substantially as herein shown and described.
